茲以驅動裝置應用於儲存系統之一實施例說明如下，請參照第1圖，其繪示本發明之一實施例之驅動裝置100應用於儲存系統200時之示意圖。如第1圖所示，儲存系統200包括資料儲存裝置150以及驅動裝置100。外部主機300透過驅動裝置100讀取儲存於資料儲存裝置150中之資料，或儲存其他資料至資料儲存裝置150中。外部主機300例如為桌上型電腦、可攜式電腦或可連結儲存系統之設備。資料儲存裝置150例如為光碟機(Optical Disk Drive，ODD)或硬碟機(Hard Disk Drive，HDD)。An embodiment of a driving device applied to a storage system is described below. Referring to FIG. 1 , a schematic diagram of a driving device 100 according to an embodiment of the present invention applied to a storage system 200 is illustrated. As shown in FIG. 1, the storage system 200 includes a data storage device 150 and a drive device 100. The external host 300 reads the data stored in the data storage device 150 through the drive device 100 or stores other data into the data storage device 150. The external host 300 is, for example, a desktop computer, a portable computer, or a device that can be connected to a storage system. The data storage device 150 is, for example, an optical disk drive (ODD) or a hard disk drive (HDD).

請參照第2圖，其繪示第1圖之驅動裝置100之方塊圖。驅動裝置100包括橋接器10與驅動器30。橋接器10包括第一控制單元12。驅動器30包括第二控制單元32及儲存單元34。第一控制單元12用以依據一操作事件輸出一指令。第二控制單元32用以依據此指令從儲存單元34中取得相對應的一筆資料，並將此筆資料回傳至第一控制單元12。Please refer to FIG. 2 , which is a block diagram of the driving device 100 of FIG. 1 . The drive device 100 includes a bridge 10 and a driver 30. The bridge 10 includes a first control unit 12. The drive 30 includes a second control unit 32 and a storage unit 34. The first control unit 12 is configured to output an instruction according to an operation event. The second control unit 32 is configured to obtain a corresponding piece of data from the storage unit 34 according to the instruction, and transmit the data to the first control unit 12.

請同時參考第1圖。當此筆資料需上傳至橋接器10所耦接之外部主機300時，第一控制單元12將此筆資料上傳至外部主機300。而當此筆資料不需上傳至橋接器10所耦接之外部主機300時，此筆資料係留待橋接器10使用。驅動器30係用以耦接至資料儲存裝置150，並用以存取此資料儲存裝置150。Please also refer to Figure 1. When the data needs to be uploaded to the external host 300 to which the bridge 10 is coupled, the first control unit 12 uploads the pen data to the external host 300. When the data does not need to be uploaded to the external host 300 to which the bridge 10 is coupled, the data is reserved for use by the bridge 10. The driver 30 is coupled to the data storage device 150 and used to access the data storage device 150.

請參照第3圖，其繪示適用於第2圖之驅動裝置100之取得資料之方法的流程圖。首先，於步驟302中，一操作事件發生。舉例來說，此操作事件例如是儲存系統200及外部主機300獲得電源供應，且驅動裝置100耦接至外部主機300時所產生。接下來，進入步驟304，橋接器10依據此操作事件輸出一指令至第二控制單元32。此指令例如用以指示橋接器10欲取得資料之請求。Please refer to FIG. 3, which is a flow chart showing a method for obtaining data of the driving device 100 of FIG. First, in step 302, an operational event occurs. For example, the operation event is generated when the storage system 200 and the external host 300 obtain power supply, and the driving device 100 is coupled to the external host 300. Next, proceeding to step 304, the bridge 10 outputs an instruction to the second control unit 32 in accordance with the operational event. This command is used, for example, to indicate that the bridge 10 is requesting information.

然後，於步驟306中，第二控制單元32依據指令從儲存單元34中取得相對應的一筆資料。舉例來說，此相對應的資料乃對應至上述指令之一筆資料。Then, in step 306, the second control unit 32 obtains a corresponding piece of data from the storage unit 34 according to the instruction. For example, the corresponding information corresponds to one of the above instructions.

接著，於步驟308中，判斷是否此筆資料需上傳至外部主機。若是，則進入步驟310，若否，則進入步驟312。此判斷之步驟係可由驅動器30之第二控制單元32來執行，或是橋接器10之第一控制單元12來執行。Next, in step 308, it is determined whether the data needs to be uploaded to an external host. If yes, go to step 310, if no, go to step 312. This step of determining may be performed by the second control unit 32 of the driver 30 or by the first control unit 12 of the bridge 10.

於步驟310中，此筆資料係上傳至外部主機300。而於步驟312中，此筆資料係留待橋接器10使用。In step 310, the data is uploaded to the external host 300. In step 312, the data is reserved for use by the bridge 10.

舉例來說，當橋接器10耦接外部主機300時，若此指令乃外部主機300請求儲存系統200提供相關資料。在這種情況下，此筆資料將被判斷成為需上傳至外部主機300之資料，而被上傳至外部主機300。否則，此筆資料將可能被判斷成橋接器10所要使用之資料，而留待橋接器10使用。For example, when the bridge 10 is coupled to the external host 300, if the command is received by the external host 300, the storage system 200 provides relevant information. In this case, the data will be judged to be the data to be uploaded to the external host 300, and uploaded to the external host 300. Otherwise, the data may be judged to be the material to be used by the bridge 10 and left for use by the bridge 10.

上述之外部主機300請求儲存系統200提供之相關資料例如是嵌入式資料。此嵌入式資料例如是驅動器的製造商名稱、資料儲存裝置製造商名稱、產品序號或相關韌體、時序資訊、或是用以指示資料儲存裝置150係為光碟機或硬碟機之資料等。然，上述之資料亦不限於嵌入式資料，亦可為其他類型之資料。The external host 300 mentioned above requests the related data provided by the storage system 200 to be, for example, embedded data. The embedded data is, for example, the manufacturer name of the drive, the name of the data storage device manufacturer, the product serial number or related firmware, timing information, or information indicating that the data storage device 150 is a CD player or a hard disk drive. However, the above information is not limited to embedded data, but may be other types of information.

另外，橋接器10及驅動器30更可整合為一積體電路(Integrated Circuit，IC)，除了可更節省電路板之空間外，亦可增加其應用範疇。橋接器10例如係支援通用序列匯流排(Universal Serial Bus，USB)介面。驅動器30例如支援集成設備電路(Integrated Drive Electronics，IDE)匯流排、串列高技術配置(Serial Advanced Technology Attachment，SATA)或個人電腦介面(Personal ComputewInterface，PCI)等規格。 In addition, the bridge 10 and the driver 30 can be integrated into an integrated circuit (IC), which can increase the space of the circuit board and increase the application range. The bridge 10 supports, for example, a Universal Serial Bus (USB) interface. The driver 30 supports, for example, an integrated circuit (IDE) bus, a Serial Advanced Technology Attachment (SATA), or a Personal Computew Interface (PCI).

本揭露書之驅動裝置及其取得資料之方法具有降低成本之優點，並可節省電路板的使用空間來更進一步地降低成本。如此，應用其之產品除了可降低成本及節省產品體積外，並可增加硬體設計的便利性，實具有市場競爭力。 The driving device of the present disclosure and the method for obtaining the data have the advantages of cost reduction, and can save space for use of the circuit board to further reduce the cost. In this way, in addition to reducing costs and saving product volume, the products used in the product can increase the convenience of hardware design and are competitive in the market.

綜上所述，雖然本發明已以實施例揭露如上，然其並非用以限定本發明。本發明所屬技術領域中具有通常知識者，在不脫離本發明之精神和範圍內，當可作各種之更動與潤飾。因此，本發明之保護範圍當視後附之申請專利範圍所界定者為準。 In conclusion, the present invention has been disclosed in the above embodiments, but it is not intended to limit the present invention.
